Back in the Spring of 2010, it seemed that every day we would get conflicting reports on whether existing Windows Mobile hardware would see an upgrade to Windows Phone 7. The consensus turned out to be a “no” after Microsoft directly denied the rumor, even after HTC Russia indicated the answer to be “yes” (which was then retracted).

But now, as news tipster MCP points out, Polish carrier Poland Telefonia Cyfrowa is listing the HD2 as getting an upgrade to “Windows 7″, which we assume to mean Windows Phone 7. If you zoom out to the selector screen as shown above, two HD2 models are shown: one with and one without the upgrade. The one with the upgrade is “on sale soon”, meaning you can’t get it now.

Could this be a typo, or a sign of things to come?

Update: The product page has been updated to reveal that the carrier is literally bundling Windows 7 (for the desktop) upgrades for HD2 purchasers. False alarm!
